## What it is
HTMLHint is a static code analysis (linting) tool for HTML, configurable via a .htmlhintrc file with many built-in rules. It runs as a CLI, programmatically via Node.js, and integrates with editors, task runners, and CI pipelines.

## Use cases
- lint html files for errors
- enforce html best practices in a project
- check html code quality in ci
- validate html attribute and tag usage
- lint html from a url
- integrate html linting into webpack or gulp
- get real-time html linting in vs code

## When to choose
- you need a dedicated, configurable HTML linter with CLI and programmatic APIs
- you want SARIF output for GitHub Code Scanning
- you need editor or CI integration for HTML quality checks

## When to avoid
- you need linting for CSS or JavaScript (use Stylelint or ESLint)
- you need full HTML validation against a spec or DTD
- your project does not use Node.js
